Applizmtioii filed April 23, 1906. Serial No. 313,212.

To all whom it mayboncern:

Be it known that I, WILLIAM G. WOLFORD, a citizen of the United States of America, re-

siding at Confluence, in the county of Somerset and State of Pennsylvania,have invented certain new and useful Improvements in Dental and Surgeons Cabinets, of which the following is a s ecificati'on, reference being had therein to t e accompanying drawings.

This invention relates to certain new and useful improvements in dental and surgeons cabinets; and the invention relates more particularly to a cabinet for rubber cloth or, as it is commonly known as rubber dam, and for surgeons bandages.

The primary object of this invention. is to provide a revoluble cabinet for rubber cloth and surgeons bandages which can be made a fixture of a dental office, surgeons operatingroom, or hospital, the cabinet being constructed to contain various kinds of rubber cloth and bandages, an quantity of which can be easily and quic y removed from the cabinet and severed or cut into the desired size. To this end I have devised a cabinet which will conveniently hold rolls of rubber cloth or bandages, the rolls being protected from dirt and dust and arranged whereby a piece of cloth or bandage can be easily obtained'from any roll carried within any of the three cylinders of the cabinet. In conneca closed position, also novel means for opening and closing thecabinet when it is desired to place rolls of rubber cloth or bandages therein.

The construction which is em loyed in accomplishing the above results is extremely simple in construction, strong and durable,

. and-comparatively inexpensive to manufacture.

which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described and claimed,

and referring to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which- Figure 1 is a perspective view of my improved cabinet. Fi 2 is a fragmentary longitudinal sectiona view of a portion of the same. Fig. 3 is a fragmentary vertical sectional view illustrating a portion of the cabinet. Fig. 4 is a cross-sectional view of the cabinet, partly in side elevation. Fig. 5 is a erspective view of one of the revoluble liea s used in connection with the cabinet. Fig. 6 is a fragmentary perspective view of one end of the cabinet. Fig. 7 is a fragmentary front elevation of one of the revoluble shafts of the cabinet. Fig. 8 is a longitudi nal sectional view of one of the shafts of the cabinet, illustrating a slight modification. Fig. 9 is a fragmentary side elevation of one of the rails of the cabinet, illustratinga portion of the locking mechanism. Fig. 10 is a pers ective view of one end of a locking-pin use in connection with the cabinet. Fig. 11 is an end view of a knife used in connection with the cabinet. Fig. 12 is a horizontal sectional view, partly in plan, of the cabinet. Figs. 13 and 14 are detail sectional views of'a portion of the cabinet, illustrating the lookng mechanism thereof.

To put my invention into practice, I construct my improved cabinet of two angular side rails 1 and 2, having their forward ends connected together by a cross-bar 3, while their depending rear ends are supported in brackets 4 4, secured to a suitable su port 5. The rails 1 and 2 are provided'witli angularly-disposed braces 6 6 to add rigidity to said cabinet. The cabinet is so arranged that it can be attached to a wall'or any perpendicular surface, if desired.

In the side rail 1 is journaled a pin 7, carrying a revoluble head 8. In the side rail 2'is ournaled a pin 9, carrying a revoluble head 10, similar to the head 8. The heads are pierced, as at 11, whereby the outwardly-extending lugs 12 of caps 14 and 15 may be secured thereto, said caps being three in number and supporting cylinders 16, which are radially disposed relative to the pins 7 and 9. With the above and other objects in view,

These caps are rescrew.22, secured in the end of said pin.

cloth or bandages is removed with them. As the pins 7- and 9 are revolubly mounted in the side rails 1 and 2, the cylinders 16 can be revolved about said pins, and in' order to lock the cylinder in a fixed position relative to said rails I provide the pins 9 with a locking mechanism. The pin 9 adjacent its end is provided with a rectangular portion 19, upon which is slidably mounted a button 20, having a knurled flange 21. The button is retained upon the end of the pin 9 by a seg- T e button is provided with an inwardly-extending pin 23, adapted to engage in one of the radially-disposed recesses 24, formed in the side 'rail 2. When the pin 23 of the button 20 engages in one of the recesses 24, it will be impossible for the cylinders to revolve about the pins 7 and 9.

Each cylinder is provided with a longitudinally-disposed slot 25, and the edge of the cylinder bordering on the slot is enlarged, as at 26, while adjustably mounted up on the cylinder at the opposite edge of the slot is a channel-shaped bar 27 ,'a spring 28 being ini terposed between the bar and the upper edge of the slot, whereby the bar 27 will be normally held in engagement with the opposite edge of the slot. In each cylinder is revolubly mounted a shaft 29, carrying circular heads 30 30, the object of which will be presently described.

blade 37 is used,'this blade being secured to the bar 3 to form two cutting edges to sever the material being Withdrawn, from one of the cylinders 16 of my improved cabinet. 45

The rubber cloth or bandages to be shielded and carried by the cylinders 16 of my improved cabinet is wound upon the shafts 29 of said cylinders, each cylinder containing a different kind or variety of rubber cloth or bandage. The heads 30 30 upon the shafts 29 determine the width of the rubber cloth or bandage carried within with cylinders 1 6; but should it be desired to mount two or three different widths or grades of rubber cloth or bandages within one cylinder spools 38 38 are mounted upon the shafts 29 within said cylinders. When the rubber cloth or bandage is in rolled form within the cabinet, the free end of the cloth or bandage is adapted to protrude through the longitudinally-disposed slots 25 of each cylinder, whereby the cloth or bandage maybe readily gripped and pulled outwardlyin order that a quantity of the cloth or bandage may be obtained. After a certain quantity of cloth or bandage has been the knife 31 and the bar 3.

withdrawn from one of the cylinders 16 of the cabinet the knife 31, which has been previously raised, is brought down into engagement with the cloth or bandage to sever the same, the downward movement of the knife causing the blade 32 to move in to engage the blade 37, this being accomplished through the medium of the cams 35 and 36, carried by After a certain quantity of rubber cloth has been removed from the cabinet and severed the knife is maintained in position by the spring-held pin 34 to sever another piece of cloth, if necessary.

The rubber cloth or rubber dam, as it is known to the trade, is employed for preventing saliva or any moisture from contacting with a tooth being treated and it is there fore essential, since the rubber-cloth is placed in a persons mouth and the bandages around wounds that the same be maintained in a clean state, free from dust and such forei n ingredients as would accumulate upon the same if exposed. The bandages are used by surgeons and nurses in tying up wounds, biindaging broken limbs, and sprains, and the li (e.

From the foregoing description it will be observed that either one of the cylinders of my improved cabinet can be positioned in horizontal alinement with the bar 3, whereby the contents of the cylinders can be easily and quickly withdrawn and severed.

I do not care to confine myself to the use of rubber cloth or bandages in connection with my improved cabinet or to the specific locking mechanism thereof, as the cabinet can be readily used for other purposes by professional men.

It is obvious that such changes in the size, proportion, and minor details of construction as are permissible by the appended claims may be resorted to without departing from the spirit and scope of the invention.

What I claim, and desire to secure by Letters Patent, is-

1. A cabinet of the character described consisting of side rails, pins j ournaled in said side rails, a plurality of caps supported by said pins, cylinders detachably mounted between said caps and having longitudinallydisposed slots formed therein, a knife pivotally supported by one of said rails, a lockingbutton slidably mounted upon one of said pins and adapted to hold said cylinders in a fixed position relative to said rails, shafts journaled in said cylinders and adapted to support rolls of rubber cloth, means to support said rails, and means to temporarily hold the ends of said cloth or bandage in the slots of said cylinders, substantially as described.
